Flowency is a science-backed verbal fluency app that helps you speak more clearly and find the right words faster. Every day you get a personalized Daily Workout built around your Verbal Fluency Skill Profile — quick speaking exercises that target exactly what you need to improve. Train five minutes a day and watch your fluency grow. Whether you struggle with word-finding difficulties, want to sound more articulate in conversations, or need to sharpen your communication skills for work — Flowency trains your brain to access the right words instantly. What Is Flowency? Flowency is a daily verbal fluency coach that uses proven language training methods — semantic fluency (categories), phonemic fluency (sounds), synonym recall, storytelling, describing, and explaining — to strengthen your word retrieval and speaking ability. Every day, Flowency builds you a personalized Daily Workout: a short, guided mix of rapid word drills, sentence rephrasing, and real speaking practice, hand-picked to target what you most need. In about five minutes a day, you get a complete, focused workout — no guesswork about what to practice. You speak; Flowency listens: AI transcribes and scores your speech, gives you coaching feedback, and updates your Verbal Fluency Skill Profile — so you always know where you stand and what to work on next. Your Verbal Fluency Skill Profile Flowency turns the vague idea of "being well-spoken" into something you can measure and improve. You get an overall fluency score out of 100, broken down into five core skills: • Flow — how smoothly and easily your words come out • Precision — how exactly your words match what you mean • Phrasing — the craft and richness of your sentences • Structure — how well you organize your thoughts as you speak • Delivery — your pacing, rhythm, and expression Your profile is built from your real speech, so it reflects how you actually talk — not how you perform on a quiz. Watch each skill grow with daily, 30-day, and one-year trends. Key Features • Personalized Daily Workouts — A guided five-minute session, tailored each day to your weakest skill. • Speaking Practice — Storytelling, Describe, and Explain: 60-second challenges with AI feedback on all five skills. High scores earn Silver and Gold Laurels. • Say It Better & Write It Better — Turn weak sentences into sharp ones, out loud or in writing, with example rewrites. Strong rewrites earn Pearls. • 1,000+ Word Gym Drills — Rapid word-retrieval exercises. Track your Words-per-Minute speed and Vocabulary Grade. • Word Collection & Journal — Every word you say is collected and rated for rarity. Bookmark words, add notes, and reveal a Word of the Day. • Gamified Progress — Earn XP, keep streaks, and unlock rare word Gems. Track it all with a calendar and interactive charts. Who Is Flowency For? • People who want to speak more clearly and confidently • Professionals preparing for interviews, presentations, or meetings • Anyone experiencing word-finding difficulties or tip-of-the-tongue moments • People looking to expand their vocabulary and sound more articulate • Public speakers, podcasters, entrepreneurs, and content creators • Those seeking cognitive training for mental sharpness Why Verbal Fluency Matters Verbal fluency — the ability to quickly retrieve and produce words — is linked to cognitive health, career success, and stronger relationships. Research shows that regular training improves verbal fluency. How Flowency Is Different • Unlike vocabulary flashcard apps, Flowency trains you to speak — not just memorize. • Unlike language learning apps, Flowency is built for people who already speak English but want to speak better. • Unlike brain training apps, Flowency focuses specifically on verbal fluency and word retrieval. • The only app dedicated entirely to verbal fluency training.
